Due to popular demand, and after a long break, here is a fifth volume of episodes from the irreverent radio comedy series that ran between 1964 and 1973.

Starring John Cleese, Tim Brooke-Taylor, Graeme Garden, David Hatch, Jo Kendall, and Bill Oddie, ISIRTA is a mix of quick-fire sketches, bad puns, humorous songs, and TV and cinema parodies. It quickly developed a cult following, and was the forerunner of The Goodies and I'm Sorry I Haven't a Clue.
